CHARGING BY INDUCTION & CONDUCTION

STARRING

THE ELECTROSCOPE

Neutral Electroscope Charges are balanced

No Reaction Neutral rod brought near

Negative charge by Induction Negative rod brought near

Temporary Dipolar charge Same charges repel Electrons move down to leaves Leaves become negative

Remove negative rod Leaves will collapse + +

Back to Neutral Electroscope

Positive Charge by Induction Positive rod brought near

Temporary Dipolar Charge Same charges repel Electrons move up to sphere Leaves become positive

Leaves will collapse Remove positive rod

Back to Neutral Electroscope

Negative Charge by Conduction Negative rod makes contact

Electrons are added Creates a Bridge Like charges repel Leaves become negative

Permanent Negative Charge Remove Negative Rod Like charges still repel Leaves stay negative

Ground Negative Charge Touch sphere with finger Extra Electrons are removed

Back to Neutral Electroscope Charges are Balanced

Positive Charge by Conduction Positive rod makes contact

Electrons are removed Creates a bridge Like charges repel Leaves become positive

Permanent Positive Charge Remove positive rod Like charges still repel Leaves stay positive

Ground Positive Charge Touch sphere with finger Electrons are replaced

Back to Neutral Electroscope Charges are Balanced
